1. Is it possible to set the point colors in a ggplot2 theme?  For example,
to default to these colors:
scale_colour_manual(value = c("red", "orange", "yellow", "green", "blue")

2. Is it possible to set this theme in .Rprofile, similar to:

my.lattice.colors = function () { .......etc.....}
options(lattice.theme=".mw.lattice.colors")
